Is there a mod that does this? indexing bot

[TaMpE]

It's like a cron job which updates a list in a thread. For example it's set to get informations in a thread and index those information in a thread we set to.

ie ...

Thread A is posted in Forum A
Bot goes and grab the following information:

Username of thread starter
Date of thread started
Link to that thread

and index these into a TABLE BBCode in a thread (not creating a new index thread everytime it does this but keeps editing and updating the only 1 index thread we set).

About grabbing information we can put some additional fields when creating a new thread and say "Infos for index bot (must fil in)" then put field boxes there. And as said about bot comes and grab information from these fields.

The bot updates the index like every 10mins or 1hour (also ability to make a new user and set that user as the bot)

Is there a bot like this already? or will it be hard to implement?
