So you've discovered a bug on the PBE? We want to know about it!
First things first though: Please take a look through the community and see if your bug has been reported already. Found something identical or even similar? Comment in that thread with your particular case, and upvote the original post for being helpful :)
Maybe you're the first on the scene with new information? Way to go! Please make a new thread with the following information to help us track down the issue:
Title: [Bug area] - Short Summary
One or two words letting us know where this bug occurs. Is it a general bug with the Summoners Rift map? Is the bug specific to a champion? Are you experiencing issues with messaging in the client? The bug area is where you can quickly let us know where this issue is occurring.
Short summary: A short description of the issue found, enough that it can be easily searched without being a full description. "[Zac] - Health blobs do not regenerate Zac's health" is a good title. "Zac health blobs broken" is not.
Body: Please include as much information as you have about how you found this bug. Steps to reproduce the issue in a list and/or activities you were doing when the bug occurred are all very helpful. Attaching replay files, screenshots, .r3d logs and your computer's dxdiag report are all excellent additions to help us figure out what is going on and how to fix it.
Here is an example bug that was reported a while ago to our live team and fixed:
Title: [Rengar] – Can double cast ferocity
If Rengar uses 5 point Ferocity E and casts W while the missile is in the air he will be able to cast an extra W spell for free with no cooldown penalty.
1. Choose Rengar
2. Level up W and E
3. Get 5 points of ferocity
4. Cast E on a target and smash W over and over
5. Notice he will Roar like a kitty twice and deal the damage. He will not get the Heal from 5 point W.
Lastly, **PLEASE DON'T REPORT BUGS IN THIS THREAD**.
