@Dema: Hmm...
First thing, it is actually possible to alter website text in Internet Explorer. You are probably not a proficient coder and I believe you when you said you didn't know that because you aren't ghost quoting in this thread - a proper coder would know how to do it.
Further, looking at your post history you are definitely one of the more active players. Because of this it's likely you know I code based on what I've said last round. Very unlikely you lied because if you know you can edit text on IE, then of course I would also.
Conclusion 1: You did not alter the PM's code.
Very odd choice for text you want to appear on this site. Times New Roman and medium sized. But people have their preferences for browsing options - I know a former player uses one of the grey backgrounds.
I believe you on not using an image manipulation program. Main thing for this - your avatar. You're a member of the Pub Club and anyone who is in it has an interesting avatar but your one is rather boring, meaning you aren't good with programs like PhotoShop. Your avatar, I can tell, is very old. Further shows you're not one to edit images.
Conclusion 2: You did not edit the screen cap of the PM.
From a technical stand point, both PMs are sound. I've changed my own browsing options and lined my own PMs with yours - the pixels align correctly. Times for them are valid, for both when the PMs were sent and what time you took the screen cap.
You are a relatively new player and it's true the Medic's ability has not been of high activity since you joined, it's understandable you're not sure how the role works so it's a possibility you just made a blunder.
Conclusion 3: The PMs are real.
