I did some thinking on the matter ... got those little grey cells just a goin' ... and here's what I came up with, FWIW ...
I think you should keep going chronologically with your *Journal* and post questions about what you are doing currently in the appropriate Technical Forum. Just remember to include your outcome in your Journal at the appropriate time.
A Journal is just that -- A record or diary of your experiences and progress. There really doesn't need to be a lot of conversation there of a technical nature. I know I have been guilty of this too in my own Journal and I am going to do better to post *my* question in the appropriate forums.
Discussions regarding how to do this, that or some other task (by you) should go in a Technical Forum.
If you post something in your Journal about something you did and how you did it .... and somebody has a question about what you did, or needs a little amplification of what you wrote, well that's fine but it shouldn't turn into something that belongs in a Technical forum.
I realize that this distinction is vague, highly subjective and possibly esoteric ... but give it a whirl, make a judgement and do the best you can. There's no Inquisition that will boil you in used motor oil if you don't do it perfectly ...
I'll do the same
