Uploading of a new blueprint

How I can make new thread? When i it tried (into Dome and Miscellaneous thread), I got this message:
"MrLotus, you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation."

Sorry for my terrible english.
Hey, sorry for bumping this thread but I'm having the same problem. Can't even make a new topic to say this haha. Probably has something to do with the fact that I registered two years ago and haven't logged in.

Also I can't see any attachments, is that the same issue?
