Hi, Im not sure this is the correct place to post this so ill check first. Ive found a nice forum on there site where you dont need to register to post a thread and you can pop your back link in... Is it ok to post it here?
It's ok to post there - I've done it a few times. However, the moderator booted me - so I suggest your link to your site is relevant to something about NASA or space.
i highly doubt NASA will have a forum where anyone can post without registering with their backlinks. there are plenty of sites with NASA domains like NASA this and NASA that, make sure the forum in question is running off NASA.gov domain which will be the actual NASA site. if you indeed find a forum like that, then feel free to comment/post to get backlinks. is it OK? well, if there is no moderation and they are allowing you to comment/post, then its very much ok to post there
