Hello there, comper-edna (or is it dna, as in compareDNA ?)
I've removed your last post and edited your former one as requested.
Sorry that your first impressions here were so offputting... but I don't think DCI's Mercury avatar comment was meant in an offensive or insulting way initially, probably just a knee jerk reaction.
You may or may not know that to increase the size of the page and hence font size for easier reading... press the bottom left Ctrl key while simultaneously scrolling your mouse wheel (if you have one) forward or backward to increase or decrease the font scale. If you don't have a scroll wheel, use the + and - keys at the right hand side of the keyboard instead, while still holding down Ctrl. To return to the default page size, press Ctrl and 0 (zero).
If you don't like any of the provided avatars, and eventually decide to use one, why not upload one of your own that you have downloaded from the net to your computer, say to the desktop.
Enjoy the forum if that's possible !
