Hello everyone! I'm going to send a formal e-mail and I'd like to know a polite alternative to "TL;DR". I think I'm gonna go with "Summary" but it doesn't sound right to me... I appreciate any suggestion, stay safe!

Which is correct (or sounds more natural)? "...so Carlos can run the tests for another project he is involved." "...so Carlos can run the tests for another project which he is involved." "...so Carlos can run the tests for another project which he is involved on." I appreciate your help guys!

Hello everyone. I'm working on a checklist document and I'd like to know which one is correct: "Check that all servers are up" or "Check if all servers are up" Thank you so much!

"A" sound Hello everyone. Can somebody please clarify if the letter "a" has two different sounds? If I say it in a phrase, for example "Like a boss", the vowel has a really and quick "a" sound, but imagine that someone asked me to say each word slowly, the vowel will sound like "ey". I'm sorry I don't know if I expressed myself in a clear way. Thank you so much

Is this grammatically correct? I just wrote an e-mail and after reading it, I'm not sure if it's correct: "We still have some machines running windows 7. For those ones, as you know the update didn’t work." Could you help me, please?

Grammar Hello guys, I'm wrinting an e-mail and I'm not sure if this is correct: "Also, we’d like to ask you to check Alejandro Gimenez and Jose Coronel’s PCs" Do I need to put "´s" after every name, or just on the last one like I did? Thank you!

Is this correct or does it even exist? I received an e-mail and the person who sent me the message said that there's no intention to blame on anyone for the negative event that occurred. I'd like to respond that I don't feel blame and everything is ok, so I used "none blame taken." Does that makes sense? How do you native speakers would say that? Thank you so much. Fernando Bueno

Question about pronunciation Hello everybody! I have a question that is killing me (for a long time actually). In the song "Wait" by M83 there's a line that says: "There's no end, there is no goodbye", they are clearly singing with a "S" sound instead of the regular "TH" sound, is it common for native english speakers? Was it just to fit in the song? Please correct any mistakes I have written. Thank you, Fernando Bueno
