Sorry to be off topic, but maybe someone can help. I want to lay
tiles in my basement. It has a good, solid concrete slab, but
previously there was vinyl tiles glued to the concrete. I needed a
torch to remove many of the old tiles, and quite a bit of old glue is
in the pores of the concrete. I hear that thin set mortar will not
stick well to such a surface (water beads up on it). Is this correct
and if so, how do I prep the surface? Thanks for the help.

There are a lot of options here.
1. you can use latex modified thinset, expensive but it will allow a
better bond.
2. You could install a "crack" membrane. Basically a sheet product that
has lots of holes that allow one side to be glued to the slab (with the
same vinyl tile adhesive) and the other side to the tile with thinset.
This stuff is used over slabs where there is some cracking, the membrane
basically puts a rubber layer between the tile and slab.
3. You could remove the vinyl glue and put the tile direct to the slab.
You use a tile adhesive remover which you can buy at HD or other stores,
but it really is exactly the same stuff as paint stripper. Get as much
adhesive off first with a heat gun, then use the stripper, then use a
belt sander to cut your way down to the slab.
Easiest/cheapest is #1, but you might have some problems if the vinyl
adhesive starts to let go.
All out best is #3, but this takes a lot of work (a lot!) and is messy.
#2 is somewhat expensive but has the advantage of covering over cracks.
If it was my house and I had planned on staying, I'd try for #3, but if
the area was too big I'd do #2. If I was going to sell in a year or two,
I'd do #1

I appreciate your post, but I posted here because people in this group
seem to know what they are talking about. They also seem to have a
broad range of knowledge regarding other areas that might be of
interest to people in this group.

Google "John Bridge Tile" and spend some time in his forum. One of the
hangouts were the 'pros' are actually quite helpful.
