I made my first topic and wanted to share a couple thoughts about the tagging process.
First is that the composer panel didn’t appear to offer me a way to add any tags. So far as I can tell, the only way I could add tags was to create the topic then immediately edit it. This seems like a very non-obvious process, and I suspect that tags won’t get used much because of this.
And second, I think every category should also be a tag. The topic I posted is applicable to PHP and to JavaScript and to databases and to server config and to hosting and to domains. Yet I had to pick only one. I think I should have been able to tag it as PHP and JavaScript and databases and server config and hosting and domains and so on.
