1. You don't need to post the same service more than once.
2. WTB means "Want to Buy," which tells people you're looking to buy a bookmarking service. You should alter your thread title to [WTS] instead.
3. You should try and establish credibility here by offering a free review copy (if one is available, I'll take it and post a review of the service). Linking to your profile on other forums doesn't help establish anything with this community.
4. If you're offering a service, you should post the details here rather than inviting potential customers to PM you.
