Prevent Doubleposting

When a User posts into a thread where he already has the lastpost, no new post will be added. The lastpost of him will be edited and the new text is put after his first message.
This will be done until the old post is older than 24 hours (you can change this timespan yourself)

Nothing more to say about that, it's the quite same as my vb3.0 version.

This Mod should run with 3.6 as well


** Please make sure you ENABLE this product after you install it - it is disabled by default. **

For vb 3.8 there are two alternative updates ;

i would love it if when someone double posts and it is merged it would time stamp the merge

The problem with that is whatever time would only be relevant to a particular time zone. So people in other TZ's would only be confused. You might want to consider that. Some people suggested adding the time difference so it would be like (added 1hr later...)

[Paul M]

The Timezone problem can be got around (like here for example).

[eoc_Jason]

The only way though would be to NOT cache the posts though. Because otherwise whoever viewed the post it would be parsed & cached for their time zone.

About the only way I can see doing this and leaving caching on would be to make some sort of javascript?

[Paul M]

The system we use works whether posts are cached or not, and has no reliance on Javascript.

Thank you SO much Kalina for solving my problem. Just tried your method and it works perfect!

My double posts now show up as:

MarcGSR added 1 Minutes and 2 Seconds later...

But still no one has answer if there is a way to time stamp them like this:

Could you please elaborate, or better yet post some code?

[Mafialife Chris]

Can someone give me a step by step in dummies terms to make this happen on my forum. This includes any actions i would need to do with my FTP and files on the server. I just do not know what to do, sorry. help?

[eoc_Jason]

Install the product via the XML upload. Configure settings in your new additional admincp options. That's it...

[coolgus]

any fix for the quick reply refresh problem ?
