"post to" vs "post on"

[Daemon99]

Can someone please tell me the difference between the following two sentences? Are they both correct?

1) Post this joke on the forum.
2) Post this joke to the forum.

Hi Daemon

I'd prefer your first sentence, but I think some people probably use the second as well.
