On the Tranlation forum someone replied thank you with:

"Tes¸ek Ederim"

In speech, espeically as Native Speakers have faster Cadence than English Speakers are accustumed to, it sounds (at least to me) just as the spelling above, but is that an accepted way to write it?

There's no such thing as "Tes,ek ederim" in Turkish. There is probably a misunderstanding/misspelling there.

It must be either:

1)Teşekkür ederim,
2)Teşekkürler.

I thought so too. Thanks.

My computer at work is a Mac, (Mac doesn't support the Explorer past version 5.2), anyway it when it encounters Turkish characters it converts them to special characters, for example the un-dotted "i" becomes ?, etc. Sorry about that.

try firefox...

Not a form of Turkish texting then? Or someone being lazy?

The short chat form is simply tşk(lr) so the form above looks rather odd since it doesn't even shorten it that much but maybe they were just writing too quickly
