As Prodigal told you earlier today, it can take 24 hours (sometimes as much as 48 hrs) for these options to be activated. Only RoboOp has the ability to confirm the donation and even he takes a day off occasionally to spend time with his family.
This is no longer the case. This site has always had problems raising enough money based on random donations yet it's users (99% of which never contribute a cent) continue to demand that we upgrade and update the function of the site without contemplating that it takes money to purchase software, pay the server bill, and just as important support the labor of RoboOp and his family.
As of August 1st the mic, pm, and some of the rooms in chat have become features only available to paid subscribers. Users who joined prior to Aug 1st have been grandfathered under the old policy, but new users will have to pay for an annual subscription to have those popular features available to them.
