I refuse to use the abbreviations that are fashionable when texting on my phone, and I still decline the verb as I always have declined verbs, so I texted someone yesterday. Illogical, I admit, as until quite recently, I would have hotly denied that "text" could be anything than a noun!
If the fashion for mobilespeak doesn't die out soon, it will affect our everyday English. Teaching Danish children English, I have already fought the battle about whether they may or may not write "How R U?" in a composition, or not. The pupils were hurt and annoyed when I said they might only do so, if the theme of the composition was to write a mobile phone text message.
And yes, I belong to the generation of schoolgirls who were not allowed to write "okay", "OK" or even "All right" in school essays, unless in reported speech- and even then if the conversation was part of an entirely imaginary composition, it would be corrected to something more erudite.
