As HoneyBadger says, and I said above: The best way to handle this situation is to create a Looking for Group listing ; even if you do not enable it for viewing in the LFG Directory you can share the link with others and have a separate Listing Discussion forum
just for those potentially interested in your game. As this has headed more for 'Specific Use Questions' than 'LFG', I've gone ahead and moved it. We look forward to seeing your advertisement in LFG soon. If you've any questions on the process of creating a LFG entry, after you've read the HowTo (in my links), don't be afraid to ask! Happy gaming!
