'Tip of the Day' toughts

[MrNase]

Hello,

I plan to make a modifiction where you can display something like 'Tip of the Day' on top of your forums.

Everything should be in a small box and it should contain small tips like 'Smileys make your posts look friendly' or 'You can use bbcode to format your posts'.

The tips should be displayed randomly. The only thing I worry is about the way how to save the entries... By now I plan to use a plain textfile which stores any tip:

This is tip number 1.
*********
This is tip number 2.
*********
I guess you know what tip this is.
*********

Do you think thats faster than a query? Remember: The tip is read out of the database or textfile everytime one reloads the forums. I plan to disable it for guests (or spiders) but Iam afraid of the server load.
