Asking a developer for an ETA can be seen, by some, as rude because they do the work for free... on their spare time... kind of like us guides and mods. Over the years, some (i.e. not all) developers have taken the stance that asking for an ETA is rude because they have to stop what they are doing to respond that an ETA is unknown so that they can then go back to keep working on developing so that 3 posts later they can go through it again (while if there was a bug reported it would be useful).
So... asking for an ETA is ok, but it's all in the way that it's asked (if that makes sense). The way you asked it, however, seems to be completely fine BTW.
But, to be clear, it is NOT against the rules of the forum (just the unwritten rules of developers mixed with a bit of courtesy (ironic as it may be)).
Feel free to PM me for further clarification or to discuss if needed.
I'm not replying to Kelmar, I just want to expand upon his explanation
Another reason why it's rude, as I've seen this happen: A user requests an ETA. The developer says Friday, for example. It's now Friday night, and people are going crazy. Like someone stole their puppy. Saturday comes and goes with more irate people demanding when the ROM/App is going to be released, et cetera. And, like Kelmar said, they do it on a volunteer basis, often for free, and to demand something of someone that is doing you a service, for free, is incredibly rude.
So developers stopped providing ETAs, because their project may not be completed at that time, or even within a week of the date, and they got fewer frustrated fans. Whenever I see a developer give any sort of ETA, it usually comes with a few caveats. Like "Soon, I have other things going on this week, so hopefully after I get all that sorted out". That sort of thing.
