I am personally quite distressed over the current crossover of cell phone text messaging to online forums. While English (either the Queen's English or the correct way) might not be your first language there is absolutely no reason to use "words" such as: u, wut, any1, sum1, or any other insane text message abbreviation.

I would have to say "u" is my biggest pet peeve. I can understand the utilization of an acronym such as "WoW" rather than "World of Warcraft" for each occurrence or very common acronyms the likes of AV, PvP, GoA, et al. On the other hand "u" is only short for "lazy". I have yet to fully understand the need to save those two characters unless for some reason your phpBB links charge by the letter.

There are excellent ways to double check your work before you post. One way would be with Firefox's built in spell check capability and the second would be a site such as spellcheck.net which also works well.

Finally, keep one other thing in mind: searching. While it may seem cool or hip to use the latest Internet abbreviations and "l33t speak" it makes textual searching impossible. Remember that the next time you reply with "use the search" and before you post. If you make things harder to find then you make the search capability much less useful than it should be.

If English is not your first language then do your best and at least run a spell check. If, on the other hand, English is your primary language then there is little reason to not make an attempt at proper grammar and spelling.
