Honestly, these are petty "problems" to argue over. The forum works good enough and getting so worked up over a few extra clicks or straining your eyes just a
little bit is pointless. Even if those "problems" are fixed, I'm sure there will be someone in the near future bring up a few more small annoyances until the forum gets absolutely perfect with tons of flashy tags and billions of fonts or some such.
So a colorblind man cannot tell the new posts from old, so what? Like said before, they are in the minority and I'm sure it's very unlikely for a colorblind person to join a small forum for game programming.
And yes, a preview post button would be nice, but the edit button works just as well. It probably influences members to go over their posts before they post them, although it may be unnoticeable to some people.
It's oh so easy to demand change, but causing the change is much harder and more demanding. If you're unhappy with the forum the way it is now (which I am perfectly content with), then by all means, offer up some help to improve it. Ranting on about the small inconveniences and the odd bug causes nothing but
more aggravation and gets people worked up over nothing.
...K, I'm done.
And just to avoid the common "That's just your opinion and blah blah blah..." I shall add a small, "This is of course all just my opinion." to the end of this post.
This is of course all just my opinion.
