How long do you have to wait before deleting discussions in your group?

Sometimes 10 seconds is enough

You can also put them in columns, for easy reference, if some of the posts have useful information. Columns are a nice feature of APSense groups

ok Radek, thank you for your information

... delete them manually :)

@Radek, the posts in my group go back to march 2012, can I start to delete them manually, or do they get automatically deleted? that is what i meant.

@Josh Only moderators and group owner can delete discussions in the group, nothing is done automatically.
Agree with Warren, not needed to wait if spamming or unrelated post (discussion) is found in your group.

lol Warren, I meant generally

Sometimes 10 seconds is enough if the post is bad enough.
