beginner proswitching + ports question

I am brand new and am not 100% clear on how the proswitching works.

The introduction walks you through configuring the gMiner to work with prohashing and that makes sense. In it, we set --algo ethash and --server prohashing.com:3339.

I see there are other potential ports and algos, but I can't ever get these to work. I guess my question is two fold:

1. Does it matter which algo + server port I connect to to enable/maximize proswitching as long as password c= is not set?

2. Can someone post an example of what what needs to be entered to connect to SHA-256 or Neoscrypt? I tried "--algo neoscrypt --server prohashing.com:3338" and similar for others, but I received a generic error.

Thanks!

Generally miner programs only work on one algorithm at a time unless it's dual mining, but I don't know if they support dual mining here. Yes it matters which port you use, you want to select the port for the algorithm that is the most profitable for your GPU. If you can mine ethash with your gpu, it's probably the most profitable right now, so there is no need to switch algo. Gminer is for ethash and equihash variant coins, if you wanted to mine neoscrypt you would use a different miner program like cryptodredge, ccminer, or sgminer. Efficient SHA256 mining requires an ASIC that usually comes with its own software.

Thanks -- yes, I have now realized I need different miners for different algos Appreciate the response!
