Second off, welcome from me, too!
I've been gaming in this scale since ... well, maybe longer than I'd care to say. First started buying, painting and basing infantry in the early/mid 1970's. But the quality of my modelling have progressed dramatically since I started participating on this forum.
I started using sheet styrene, cut into small squares. I've tried cardstock, and balsa. I have finally settled on pennies.
My standard basing approach these days is to mount 4 or 5 infantry figures on a penny as a standard squad. 3 figures is a "special" squad (engineers, larger command squad, etc.). 2 figures is a sub-squad support stand (LMGs, MMGs, infantry mortars, commo teams, observer teams, etc.).
I used to use white glue. I have since, on this forum, learned to use acrylic medium matte gel, which I buy at my local crafts store ("Michael's"). I find it much easier to use. It has the consistancy of pudding, it can be colored by mixing in any acrylic paint, it provides color, texture, and adhesion all in one. I mix it in with cheap crafts paint to give me a dirt color, I slather it all over the penny, push the painted infantry figures' molded-on stands into the glop, touch the tops of those molded-on stands with a touch of the medium, then dump some scattered sand, railroad shrubs, and flocking all over it, and set it aside to dry.
Now, on to some pictures, moving forward from my first pennies, to my more recent stuff:

The Soviets in the background of this recent game pic were the first units I mounted on pennies, more than 15 years ago. I used white glue. I refurbished them about 3 or 4 years ago, adding the flocking and some added detailing. But still they are fairly primitive by my current standards.
In the foreground is a squad of my Italians (in Continental uniforms, for service on the Eastern Front). This was my first force to be painted and based since joining this forum. The basing again used white glue, but in this case the glue was mixed with paint as it was used, and the flocking (and detailing) were done from the get-go.

Here you see the Italians again -- in this case an AT gun and an HMG trying to stop Soviet tanks from crossing a bridge in the background.

Here are some of my Romanians, the most recent force that I've put together. These use all of the techniques I described above. I'm very pleased with the results.

For my artillery I have set up crews on bases, but left the guns loose.

In this way I can use the same based figures to provide light or medium gun batteries as my gaming needs vary.

I've done the same with my AT guns.

In thise way I can provide a battery of AT guns for 1941, or 1943, or 1944 forces with only one set of crews.

Closing thoughts with a close-up of my current work-in-process, French Armee d'Afrique troops.
What I have found is that pennies are pretty robust. They are also pretty economical (I get 100 per dollar). And they are easy to find, even around the house as needed. Few things I find as frustrating as being just 2 or 3 bases from finishing, and having to wait for another order to come in in the mail. As it is, I can just go look between the cushions of the couch.
That's my approach. Your mileage may vary. Good luck. Have fun. Post a pic or two so we can have fun looking at what you are doing.
