Unmaintained Double Post Preventer 1.5

Is easy on RAM (low resource usage) and keeps my forum nice and tidy from both intentional and unintentional (glitch/internet lag) double posting. The newest update is excellent, as always from the addon's author.

Great add-on. Light, easy to configure, does exactly what it is supposed to do.
Would also be nice to add a possibility to put in the delimiter text the time passed since the previous post, e.g. "Posted after 15 minutes".

Great add-on, it works great and keeps our forum nice and tidy. Thank you for not including any branding or strings attached.

This add-on is exactly what my board has needed since it opened. We have a major problem with people double-posting and continuing to do it even when given a friendly reminder by a moderator. When some of the known bugs are fixed, I will give it five stars. Thanks for this great add-on!
