Heya Esequiel, so nice to hear from you!
I definitely plan on doing some youtube videos! I'm trying to get my friend to do them who is a little better at doing them than me but it might be time to bite the bullet and do it
I actually have a bunch of new stuff I've added to D.'s Sandbox so I can do an even better release.
The image gallery was a phpbb mod that unfortunately didn't convert to the updated version of the forum software. I still have all the images and I think I might just do a wordpress gallery with them. There is a gallery mod for the newer version of phpbb but it is still very much in development. I'm super open to suggestions! Honestly I never would have upgraded if the host updating php didn't break everything, so sorry about that but it definitely was never my intention.
Take care and have an awesome day!
