| Could someone please expalin 'IM'?
It may seem silly in this day and age not to know how to work this but I am new to all of this. My sister-in-law asked me to 'IM' her and I asked how? I have never used it and really I kind of ignore it when it comes up on my computer. I have registered but have never used it, nor know how to.
I do know that it may be easier than I think it is, as always. I don't think I could mess up anything if I just try and use it, could I? But it may be annoying to someone else who may not know I don't know what I'm doing. |
