@JTT,
I was in the middle of explaining but my time ran out and was cut off. It is a legal logical argument. It is a complex sentence composed of many sub sentences:
Condition 1. We may change these at any time
Condition 2. We will do our utmost in informing you
Warning: It would be prudent to review this regularly yourself
Condition 3: Your continued usage of SPCF after changes
There should be a comma after "changes"
The "mean" refers to those conditions and therefore plural.
Logical conclusion: You agree to be legally bound by these terms as they are updated and/or amended
Quote:We may change these at any time and we will do our utmost in informing you, though it would be prudent to review this regularly yourself as your continued usage of SPCF after changes mean you agree to be legally bound by these terms as they are updated and/or amended.
