Can I sell lindens if it says 0 or do I gotta go to my account that can sell them?

[MeyganaMay]

My buying balance says $30 but the selling say 0 what do I do

Your trading limits stay at the newbie level ($30 for buying L$, $0 for selling) until you have bought L$ at least once.  In the year since you joined SL, you have apparently never bought any L$ through the LindeX -- buying from an authorized third party reseller doesn't count.  After you have made your first purchase, the limits will start to rise automatically.  You may request a review of your account to increase your limits by submitting a support case:

1. Under What type of problem are you having? select Billing.
2. Under Billing, select LindeX Billing and Trading Limits Review Reqest.
3. Fill out the remaining fields as instructed, then click Submit.

Linden Lab will review your request and get back to you within five business days, which is about as long as it takes for your limits to start increasing anyway.
