Ehy guys,well i fully joined the thieves guild,yet i notice just today that the misc. objective to speak to Brynjolf about joining the guild is still active.Odd enough.I tried to talk but he seems to be busy and no choice answers can be popped up.It is a glitch or something?

Jep - it's a bug http://www.uesp.net/wiki/Skyrim:Thieves_Guild_(faction)#Quests
