I'm not sure how to explain my problem properly.
Situation is such: my university offers a free domain to all students, and it basically works by putting website files into the properly named subfolder that only you have access to. Currently, I've got a basic html site hosted in this manner, but I want to have a blog, so I'm thinking of transferring to wordpress. I honestly have no idea where to start from since I'm just your garden variety physicist and googling isn't very helpful.
If I understand correctly, I would have to install wordpress on my university's host computer, and I don't have the privilege to do that.
