Yes I know where you got the name from. But I've only ever heard "remedial" used like in your example, "remedial math." The context of which is that someone was having trouble with math and needed extra help to catch up. Which would imply that the comics you host need extra help to catch up, to be on par with other webcomics. Which seems like a negative connotation to me. I understand that it doesn't have to be negative, but I was just letting you know that it could be interpreted that way.
It's like in the fifth Harry Potter book (sorry, it's the best example I could think of), where Snape is giving Harry Occlumency lessons, but it has to be a secret, and Snape doesn't like Harry very much, so he uses the cover that it's "Remedial Potions" to humiliate him, because it emphasizes how Harry is supposedly bad at potions and needs the extra help just to keep up with his peers. Similarly, whenever I see "remedial something," it would seem to have the same negative connotations.
I guess your intention is that the comics themselves are actually the "extra help" for people who need help with boredom and appreciating comics, which works I guess, but it wouldn't have been my interpretation from just hearing the name. And even then, it's still implying that the readers need extra help to appreciate comics and correct their boredom, as opposed to people who read "regular" webcomics that don't need this "extra help".
All in all it's not that important, but you can't deny that can be mildly offputting to some when interpreted a certain way.
