[Anyone have any experience with running a silent auction?]

This is for fundraising for our charitable trust with donated items.  I have found some items on Marketplace that involve a person bidding on an item, paying for it, and if outbid, the last person's money is refunded, but would like more control than that.  Thanks for any ideas!

[Clickable link to group profile]

Hi....I have received links either in chat or in a notecard, which allows one to pull up a specific group's profile in order to join that group.  I have done some searching and cannot seem to figure out how to create that clickable link to our group to imbed in a notecard.  This is much more convenient and direct access than friends having to search and locate a group in order to join it.  Thank you for your help!
