Hello Dotoar! Welcome!
You don't have to worry about how long you'll last if you follow simple rules concerning advertising and self-promotion. If you haven't you can read forum rules here:
http://www.musicbanter.com/announcem...rum-rules.html. If you have the time to look around a bit, you can see that this is a community for music fans to discuss, debate and share their thoughts about music in general, specific bands, genres etc. We have many interesting discussions here and one section of the forum that is especially of high quality:
The MB Reader - Music Banter, where members post their reviews, journals, lists etc. So, you can see what kind of forum this is.
Sharing your own music can come later, after you prove yourself to be a contributing member of the forum who's not here just to promote his music. I'm sure you have interesting things to say, so, please stick around.
