First off, you can't put up a post on the forum to promote your band/club/gig etc. That's because it's spam, and we don't allow it because the community don't like being spammed.
GlamRock.com has tools and resources specifically for bands and promoters to engage the community to drive attendances for their events.
Here is a step by step run down how to use the available tools and resources -
1. Add and make friends from your profile page. Look for people that may be interested in what you offer, befriend them, comment on their pictures and post on their Wall.
2. Create a Fan Group. List the details of your project.
3. Once your Fan Group is approved, upload pics and video's. Provide enough content to do your project justice.
4. Contribute on the GlamRock.com Forum so people get to know you. Build a reputation for friendliness, approachability and knowledge. Become a resource. Demonstrate that you know something about hard rock which lends immediate credibility and attractiveness to your project.
5. From your Fan Group page, start inviting your friends to be followers of your project.
6. Start posting bulletin updates to what's happening with your project.
7. When you have gigs/nights on, post them as Events, send out invitations, upload your gig/event flyer.

That is the cheapest and best way to do it.
It takes time and a little patience but the results will be there.
