Fro the last few years, I contacted a boatload of forums - I sent the list previously. I did that twice each and maybe a fwe more times if there were posts made that I could respond to.
Altogether, it was a few hours time -- most of it spent setting up the forum accounts. Most time after that was just copy and paste, maybe update a few formatting codes.
I won't be doing this again but it's not a daunting task. Just calls for some typing.
Additonally, there was an ad in TAG that someone made.
I think that was about it in the past, iirc.
I think it would be best to cover those bases. If anything else is contemplated it can be icing onthat cake.
