Hi, my name is Diana and I am experienced in working with forums. I have recently started to develop my interest into SEO as well, and I've done link building through forum posting for some clients. I can also help you improve your SEO ranking through other methods, like keyword optimisation and more.
The research about inventions and patents wouldn't be a problem either, as I'm very comfortable with Google searches. What I would advise, though, is to allow more days for forum posting in order to make everything appear more natural to both users and Google's algorithm.
If you're interested, please contact me whenever it suits you best.
