There's no edit butan on uboa, though, so your point is moot. /tkki/ usually makes threads for different number versions (i.e. one for .100, one for .101), and .flow's updates are too sporadic in comparison to keep one thread and just update it whenever it does pop up.
Also, there's the link to the wiki in the help sticky on /tkki/ which almost always features the latest updates.
God knows I fucking miss that button.
Sei, is there a possibility to get that again, or we should've gave up on it already?
P-Peacockfeather, is that you?
Unfortunately it's not likely to happen any time soon, since it would require some involved modifications to Tinyboard.
Edit: Also, please note that you may ask an Administrator on IRC to edit your post for you (Praesul, Writer, Yui, or myself).
There is a mod edit feature that cannot easily be made per-user accessible.
