[Where is the "Sell Land at Auction" button located?]

Just put land 'for sale'.... and keep lowering price until it gets snatched up. If you price it below L$1 per sqm it ought to sell fairly quickly (a week maybe - which can be a lifetime in SL!!) 

I never did like how auctions worked out anyhow. I believe you can 'request' to buy abandoned land at L$1 per sqm via a Support Ticket. But to get rid of it, quickly, abandoning is only choice. 

[Main Land Tour?]

Check out VRC (Virtual Railway Consortium) Freebie Wall. Get a Feebie "Hobo Train". Rez it at any railroad 'rez zone'... start it up and let it GO!  Endless rails, easy to drive.. mostly just riding, once you get it moving.

When you get your Freebie train.. rez it right on track behind you... and GO! Many other train landmarks are available on Station wall that across the tracks.

I'm laughing out loud at your post, because it's kind of "griefer-ish" and nice to know people are still having mischievous fun.  If I was to see you buzzing over my tree tops, I would cheekily board your helicopter as a passenger!

I've had several boarding passengers as I fly around!  They just TP-sit right in with me.  One was quite interesting to chat with as we buzzed around north of the fairgrounds.... a cat avi as I recall. (I fly extremely low... under bridges and all... my copter is not that big, MUCH FUN for me... and being able to set-down on water ANYWHERE is a plus. 

'Griefer-ish' ... is if I turn on it Siren! and Search Light..... could do dat RIGHT into a couple's window!!   (Nah... I'm not DAT mischievous..... (maybe!))

That's such a great idea!  I always yell hello or blow my horn on my boat when passing by people - probably annoying as hell

I get around in a helicopter.... don't ya think that's annoying when I'm buzzing thru their treetops!!!  LOL I have been known to intentionally 'buzz' the lil green dots of the map... but I don't hang around long. It's my neighbors that has to put up with going in/out all the time. 

BTW it has floats too... so doubles as a boat. 

[freinds cannot open doors in my lindon home and he has full acess to it]

I had a problem like that.. where I couldn't open my door (in old Linden Home.. not these new ones)

I had to do a support ticket thing.. and someone came out.... (with a lil flying Ferry avi) and fixed it while I was standing there. 

I'd have to bet that 'changing out' the house from mailbox then back to the one you want will fix it. Tho I've done that and I believe it resets all back to default... dunno for sure. Give it try, worst is you'll need to re-enter preference and perms. 

Btw.. you won't need to 'redo' your furniture or decor... it'll all be in wrong place with temporary floorplan. When you switch back to your chosen floorplan all will still be right place.

is there an official changelog? 

Here in Forums... Technology section, weekly deployments! Will tell you ALL in mind numbing details. 
Is best to watch all the regular forum “chatter”... if any major changes are happening, someone will be chatting about it!

[Why does my Avatar looks like fog or egg?]

What's worked for me... to 'fix' this problem is to 're-wear' skins and shapes. Seems to be a 'bake' failure.

 

Just 're-wear' a complete Outfit will most likely work, if you've saved skins/shapes in your outfit inventory. Overall... it still takes some time to 'bake' to a proper appearance, give it all a few more minutes to straighten out for you!

[how come my mama allpa doesnt work... i tried clicking the two symbols but nothing happens]

#1. The region/area that you are in at the moment MUST allow it. No "G" or maybe "PG" areas.

#2. You need to be near someone of the opposite sex, near you, that is also wearing the HUD.

 

I am not an expert.. just an interested user. It's been fun although seems there are a lot of Avi's just learning. One girl asked me... while in-world... if it was 'polite' to open herself to me?... Well.. I guess SO!

I see they've put up a classroom... have not seen any 'class events' tho.
