Is it 'indicative of' or 'indicative for'? Where do I put commas? Should I use 'to provide' or 'to enable'? After spending months writing my PhD thesis and spending even more time on language editing, I became blind to my own errors. That's why I decided it is time to let some native speaking professionals do their work and handed my thesis to the proofreading service of the PhD People. And I must say, I'm very happy with how it turned out. The process was fast, and the arising questions were answered promptly via email. It was even possible to discuss the corrections and have them reread free of charge. I can now confidently submit my PhD thesis. Thank you very much!
