@anonymous $10/mth to do wordpress
Just so you know, you can definitely make a small WordPress site work well on the $5/month option. There's some stuff you will want to be able to do in Linux/WordPress before doing it on a production VPS, namely swap file management in Linux and site caching in WordPress, but once you have those down you might be able to save some money on hosting 🙂
Might be worth trying out if and when you do a test restore of your site. If you do want to test it out, keep in mind you'll have to do the restore from a WordPress-level backup and not a Digital Ocean server snapshot/backup - they don't let you restore those to a smaller-sized VPS.
With all that said, their $10/month option is what I would pick if I were planning on hosting a forum on the same server.
