Sorry but doing that contravenes Forum Policy.
Those policies specifically mention providing links in posts that solicit people to leave our site and join a competing service, and of course that is just common sense.
That restriction also extends to messaging the members here privately.

Dear moderators/admins, may I please send a few members here private messages asking them if they want to join my forum? It's not like I'd spam people about it, I'll just ask them if they're interested, and if they are, then they can join and post, if not, that's okay too. It's not related to money or "rewards" or scams or anything like that, it's just a forum, similar to this one. So, may I please have your permission to send people private messages? Also, may I please post a topic about my message board on your forum?
