Happy Holidays, everyone!

I've started on the maginifying glass today. The image is attached.

Now I have a few questions:

1. Housekeeping: Can we get a sticky thread for this? Either this one or a brand new one with a more specific title?

2. How and where do we upload the WIP files for others to look at?

3. Do I need to UV map this and how do I do this right?

Right now if I go into the UV map view, the thing looks scary. And I have no idea how to make any sense of it.

4. What about scale? Right now this thing is huge. Where do I scale (assembly room? modeling room?) it and how do I do it correctly for best usability?

5. This is a single vertex object with multiple sub-objects and shading domains. Is this the right way to do it or should I be separating all the internal objects into assembly-room objects and grouping them in the assembly room?

I am also using Carrara's smoothing. Is that a good thing to do or a bad practice? The model does look a bit different when smoothing is disabled. For example, the glass does not match the frame when smoothing is changed.

I'd like for someone here who is better experienced at modeling to take a look at the model itself and tell me what I can improve about it. Hence the question of how and where to upload it.
