20. Troubleshooting, section 20not done
21. Index, section 21 (this is not likely to get done, unless someone helps)

I have done my best to make these pages as accurate and complete as possible, with hyperlinks to appropriate pages in the manual and external pages as appropriate.

When possible I’ve included helpful information like alternate tools, dimensions of parts, hints and tricks, etc.

However, humans are imperfect, and everything can be improved.

Here are some things I’d like feedback and help on:
(a vaguely ordered list, clicky email links)

1. Technical errors
2. Spelling errors
3. Broken links
4. Hints and helpful info
5. Formatting errors (or improvements)
6. Style inconsistencies (or improvements)
7. something else I’ve not considered

If you have some helpful feedback on any of the above, or something I I haven’t thought of, please send me mail!  I can’t promise I’ll fix it quickly, or agree with your stylistic changes, but I’ll consider everything.

Here’s a Style Guide I’m attempting to follow.
