I'm not going to bother explaining my last post as you are very rude OP.
If you read that as rude, that's your prerogative, however, you didn't answer the original q I asked, (or anything, actually) and the post you referred to had no relevance to what I actually asked, so I'd really question who was being rude here, as it appears you just popped up for a snipe. And yes, then came back for another.
OP I'm not sure what you want from this post, you're unnecessarily snipey with people who are answering your question which to be honest is simple maths.
As stated more than once, an answer to the q I originally posted in the thread title? If it's just a matter of simple maths, why isn't the answer a simple yes or no? Because there are small factors which differ for ppl, which they have been kind enough to elucidate in their answers. And I have already expressed my thanks a few times about that. Nothing snipey about that.
I may have been snipey (if you choose to read it as such) about comments which have been judgemental, rude or deliberately ignorant though. I never told anyone to rtft or anything like that, so I hardly think my comments have been rude at all! Anyhow, it's obviously some ppl chose to make that judgement regardless.
Yes, I obviously do need help. Some ppl have kindly given ideas, which I have thanked them for and said I'll look into. My situation is not good on a number of levels right now, and it's not easy seeing the way forward. This was a simple q which (as always) someone has chosen to use to kick a stranger when they're down. Again, thx to those who commented supportively.
