First this thread is for the Mod or websit problems, So you just need to post some problems you are having, for now the mod isnt out yet so the problems will be mainly about the site,
il try now and tell you some things.
For the signatures, i have tried to find a way but it doesnt seem to work so i tried something out that works fine.
Go on where you can post a new topic, click on ImG option to import and image from the net. type in the adress. when you got it copy and paste the code and adress in your signature option. It should work fine.
