I think by facebook or some general social media sites having a page won't help much,  but find those groups which is related to webhosting and designing and share the offers to the group, it will help. Also communities focusing on the same will help in boosting the forum further, conducting some kind of contests will also help people join.

Exactly thanks @Littlemaster. That is what I was hoping for. That any of the members with access to communities like that can use the suggested note that @Dynamo created (in my OP and below). Members don't have to refer to it being from Dynamo, you can make it your own, and shorten or lengthen it as you wish. But this would mean a lot for all of us if you could spread the message below to related communities.

Hello Guys,
Today i am going to introduce you guys to a forum that provides free VPSs to users who are active in our Forum. Post4vps.com is a VPS tech forum where you can learn and share knowledge about how to get cheap and free VPSs. Members also share their knowledge about other free related services. You can check out the Forum's available VPS Plans here:

How Users can get Free VPS?

Answer: Users just have to join this forum and do 25 posts (nice quality) and take part in VPS Giveaways which happens on the 1st of every month. Then to keep the VPS they have to make 20 posts per month.

The Forum uses NewPoints Plugin to recognize the size and value content of the posts and it calculates the score into dollars. Users must have equal to or greater than $100 credits in their account before they can make a request for a VPS. But it doesn't take long to get there.

The owner of the Forum wants to help those users who want to learn about using VPSs or don't have money to get VPSs for the applications they want to run on a VPS. The VPSs at post4vps are provided by sponsors who are promoting their VPSs. They are all high quality VPSs with very good specs and suggest you check them out here for a comparison of what is available.
