If you try to use the `/discourse` slash command to watch multiple tags with the official slack plugin, it doesn’t work.
After doing the following:
```plaintext
/discourse watch tag:foo
Watched tag foo
/discourse watch tag:bar
Watched tag bar
```
When you look in the admin page for the plugin, you can see that the channel is only subscribed to the `bar` tag.

@vinothkannans I think we should support something like `tag:foo,bar,..`

For categories, if I watch one, and then another, I now am watching the union of those two categories. I think it should work the same way for tags. So, for instance, in the example in the OP, I should now be watching both the `foo` and `bar` tags.
In addition to doing this for the sake of consistency with the UX for categories, consider this case:
User A uses some combination of slack commands to watch 7 particular tags in a given channel.
A month later, User B thinks the channel should also watch some 8th tag.
If they just do `/discourse watch tag:number8`, it’d be unfortunate if that silently destroyed the work of User A from a month before.
…
There should probably be a command to un(watch|follow|mute) tags and categories explicitly instead if you want to stop watching any of those first 7 tags.

Our current design makes zero sense if it is overwriting every time, as already pointed out, nobody would expect that once you watch a category all previous category watches are erased. Why would we allow that for tags?

@tgxworld that’s why I didn’t update tags [here](https://github.com/discourse/discourse-slack-official/pull/22/files#diff-b61ae67bc6a57a3decb8d15b832077f4R337). It will overwrite existing tags list while processing slack command. May be you missed it while merging. Shall I make PR? Or is there any other option or best practice?
Else particularly for slack commands we should do append behavior instead of updating.

Thanks @mcwumbly. Fixed with tests in

I think you’re looking at the wrong spot. That comment in the link is referring to `DiscourseSlack::Slack.delete_filter` where it broke because it was only matching against tags and not the channel.

Just tested this out and it’s working great, thanks!
