It might be fascinating if we exchanged our reasons for turning to Lulu, and I'll kick it off.
I was a single dad of four children for what seems a lifetime. Anyone in that position knows it can be pretty soul-destroying and that the first thing to suffer might be the old social life. To a certain extent that happened to me, but quite early on (1985) I bought a computer for the children and with it came "free" word processing software. This reminded me that I was trying to write a novel in my spare time, using a portable typewriter and spending a silly amount of time retyping pages because of the inaccuracy of my typing. The computer was an Amstrad CPC 464, loaded via a cassette and the word processing software was pathetic. But I got going and very soon upgraded the software and bought a machine with a disc drive. Most of the stuff I've since put onto Lulu had its birth pains back then.
Over the years, and in a kind of desultory fashion, I tried to engage the interest of both publishers and agents, but with no success. Once or twice a few sample chapters were requested, but that was all. I got to the point of falling out with the entire industry because, I told myself, it's taken months or years for me to write something and they reject it with a brief impersonal note (the most offensive was two words, no thanks) that doesn't even give the impression that my synopsis has actually been read.
I stuck with my Amstrad CPC for years (the kids had moved on to better, faster machines) and the pile of texts grew. I stopped putting them onto paper because, frankly, it was too expensive (not in paper, but in ink!) The PC came along, and I transferred the whole kit and caboodle onto that. (I used a wonderful little free program called SANKO that saved my chapters as RTF that actually worked in MS Word.)
And that might have been that had I not been watching BBC Breakfast at the end of last year when Lulu was being promoted. The rest (to quote the old maxim) is history.
