Workload, mainly. I do a lot of homework in the morning and access Iwaku via my phone, which can cause issues.
Have you ever tried drafting posts on paper during the day? Or on a laptop, if you have one?
When I was in high school, the wi-fi there was blocked for students -- but I
could load the most recent page of the IC while I was still at home in the morning, and then,
so long as I didn't try refreshing anything, I could keep that page up even when I didn't have internet access, and then use that to write a post. I of course drafted the post on Word, though, and then copy/pasted it onto the site when I got home.
If you don't have a laptop, though, you could always just draft the post on paper and then type it up later. And if you can't recall all the necessary details about the IC from memory, then you can try printing the posts out and bringing them to school with you. I remember I did that once or twice when I was
really desperate. ...Not sure
why I had to do that, but I definitely remember doing it. o_o
Or!! If you're not in any convenient position to sit down and write a post, but you can think of at least
a few bits and pieces of the post that you want to include (which I know you can, having discussed it in PM's already) then you can whip out your phone, write a few lines in a text message, and email it to yourself (as you can type in an email address in place of a phone number when writing a text message and it'll send it to that email address -- works on virtually any phone, even non-smartphones). Doesn't even have to be coherent or have the sentences in the right order or anything. Just type out the parts that you want to include. It's great at getting you started, and, well, I can think of quite a few times I've done this when I wound up writing almost the entire post like this. O_O All you have to do once you're back home or whatever is to access your email and copy/paste everything together, and add whatever few bits are left to add. I know I've done this quite a few times when I was out-and-about, just running errands with my mom or something.
Hopefully at least one of these suggestions works for you. ^^"
