Good luck with your workshop.
It is probably true that if it didn't have any of the alternative printing items in it it would be outside of APUG's focus, but that wouldn't mean that most here on APUG think that it would be bad.
If there was a digital component to everything you do, it would just be that APUG wouldn't think that it was particularly suitable for discussion on APUG. And you might be asked not to advertise the workshop - but most likely not.
By limiting the subjects on APUG, the site has kept itself very focused, and as a result healthy.
A lot of APUG members are familiar with or use some digital methods - they just know not to discuss that stuff here.
There are quite a number of members who choose to darkroom print all their black and white work, and don't do alternative photography printing. Obviously, they are not your target market.
