Thanks

Make sure, that "Use delimeter for forums posts" set YES.

According to screenshot, you defined delimiter message, but fogot to define where to apply. That can seems a duplicating functionality, but it's needed for other addons, which defines more complicated conditions for delimiter appearance.

Sure, delimeter text is ON
run test with merge time 60 min

test with time = 60 min is OK
thanks for your precious support

confirmed doesn't work here either...
It merges but no delimiter text...

The add-on does not work for me.

Please, be more detailed. I have low tepelathy skills. Addon is working.

thx for the mod, works on 3.8.5 :)

Sorry, unicode only. Search recoder program in google, there are should be some.

for ubuntu "apt-get install recode" :)
