Hi,

im FAQ von MyLittleForum steht dazu:

Is it possible to edit my message when it’s already posted?

Editing is possible only for a certain amount of time depending on the installation (often 12 hours) after the original submission. Open your post and click on the edit-icon in the lower right hand corner.
We would recommend to use the preview function to keep editing of already posted messages at a minimum—it may be confusing for readers if there are already replies and the original post is changed.

Viele Grüße, Ralf
