No the means it was intended to be funny and light hearted and to keep the tone of the answer light.
but to take your point further the reason for extra information being needed is that your suggestion of 'if you are using theme xyz do this is not practical because of the sheer number of themes both in and out of core - there are 40+ in the addons directory alone, more in core and add in themes created by NSL or other bespoke themes, then there is the version of moodle and the theme being used which would impact ont he response, so that it is not even possible to say in some cases, in this theme do this, in this theme do that - when a simple request for more information from the OP - if responded to - can sort the issue with specific instructions very easily. At least we know from the 'additional HTML' reference that its not Moodle1.9!
To take your point to the extreme - how would you expect a forum to respond to the query ' my computer doesn't work, please help' - on your logic the forum should then bend over backwards to list an entire troubleshooting manual that goes all the way from 'is it plugged in' to xyz component is malfunctioning causing such and such effect. and is unlikely to be of any use to the original poster!!!
Perhaps the theme forum header should refer to a link Joseph posted in a recent thread in another forum about how to ask smart questions on forums
I am aware that as people who respond to these questions it is essential for us to try to understand where the request is coming from - but it is also essential for those asking the requests to understand where the help is coming from.
This is a community site made up of people who volunteer their experience, learning and support - it is not a paid support help-desk - and my experience is that if you ask the right questions you will get a far higher level of response than you could ever hope to from a paid helpdesk!!! However, if you want to throw criticism around then there are several options - find the help yourself, offer it to others and become part of the solution and take the opportunity to do it your way, or post what you like but dont expect a prompt reply!
Now, as I originally stated, both to the OP and to you previously, if you have a question about a specific issue that you want help with then please ask and give us sufficient details to be able to help you with, other wise the reponse is likely to be something along the lines of RTFM or in this case RTFTutorials posted at the top of the forum as suggested in the linked document - although we tend to be much more polite and helpful about the suggestion on here! - no sarcasm and no offence over the language intended, trying to keep the subject matter light!!!
