Hi glenn, sorry but I have to disagree. one letter imo would be best. How many people search by using a phrase.
"How to disable rightclick"
Or "getting IP"
Or "Using css to change links"
Fact is, people use phrases to search. Now, I don't personally, I like to make my searches a little more oriented and large
So, I don't know if phrases will work or not, if phrases will then I agree with you 100%. Otherwise it also becomes an issue.
But then again I don't mod this forum and don't know what kind of stress is put on it. So you may be better off by limiting searches a bit.
But yes, if you guys can atleast make the minimum 2 letters that would be great. Much easier and greatly improved. I myself thank you for that alone.
